SYSTEM DESIGN
General
Valcom Amplified Recessed Ceiling Speakers may be used to
provide one-way paging from any Valcom one-way or talkback
page control. The speakers can also be used to expand
existing 70V paging systems. When power and appropriate
input signal are applied, a voice page can be made.
Page Control Access
(See Figure 1)
When using the Amplified Recessed Ceiling Speakers with a
Valcom page control, the following equipment will be required:
• Appropriate one-way speaker assembly
• Valcom page control
• Valcom power supply sized to provide power to operate
the amplified speaker assemblies and page control
NOTE: When using the Valcom one-way interior
speakers with a Valcom handsfree page control, it is
recommended that a V-1092 Volume Control be
connected between the zone output and the speaker
input.

25V or 70V Paging Systems
(
See Figure 2)
When using the Amplified Recessed Ceiling Speakers with an
existing 25 or 70V paging system, the following equipment will
be required:
• Appropriate one-way speaker assembly
• Valcom power supply sized to provide power to operate
the amplified speaker assemblies
• Valcom V-1095 70 Volt Expander
Special Applications
The Tip and Ring input of the amplified speaker may be
connected directly to the speaker in most electronic key
telephones to amplify the level of the speaker. A power
supply is also required.
Speaker Cabling
All Valcom amplified one-way interior speakers require 2 pairs
to operate. Standard telephone station cable may be used.
Existing telephone wire and feeder cables may also be used.
Refer to the following tables when planning an installation.
• Audio Pair: The number of speakers looped on the audio
pair is not critical unless you have a very large job. Table
1 gives guidelines for the number of speakers per audio
run.

1600 25 15
• Power Pair: The cable runs specified in Table 2 are very
important and must be followed for proper operation of
the one-way paging speakers.

Coverage
The area covered by Valcom Recessed Ceiling Speakers is
determined by the height of the ceiling. If the ceiling height is
8', the speaker will cover 250 sq. ft. If the ceiling is 20 feet
high, the speaker will cover 1000 sq. ft.
INSTALLATION
Typical connections to a Valcom Page Adapter (refer to Figure
1)
• Connect screw terminal marked Tip to the tip side of the
desired speaker output of the page control.
• Connect screw terminal marked Ring to the ring side of
the desired speaker output of the page control.
• Connect -24VDC "B" battery (may be referred to as "-" or
"signal battery") from power supply to screw terminal
marked -24VDC on the speaker.
NOTE: "A" battery may be substituted for "B" battery
connections.
Connecting arrangement to 25 or 70V paging systems (refer
to Figure 2)
• Connect 25 or 70 V paging system to V-1095 as shown in
V-1095 instructions.
• Connect one output of the V-1094A to screw terminal
marked Tip on the Valcom amplified speaker.
• Connect the other output of the V-1094A to screw
terminal marked Ring on the Valcom amplified speaker.
• Connect -24VDC "B" battery (may be referred to as "-" or
"signal battery") from power supply to screw terminal
marked -24VDC on the speaker.
• Connect -24VDC Ground ("B" ground, "+", or "signal"
ground) to screw terminal marked GND on the speaker.
NOTE: "A" battery may be substituted for "B" battery
connections.
Mounting - General
Mounting of the Amplified Recessed Speakers is
accomplished utilizing a mounting ring or backbox. The
V-1012BB is equipped with a backbox and support rails, while
the V-1011MR is supplied with a mounting ring and support
rails. See Figures 3 and 4.
Mounting Rings and Backboxes:
• Provide support to prevent ceiling tile from sagging from
the weight of the speaker
• Provide receptacles for torsion spring installation
• Mounting rings are constructed of 20 gauge cold rolled
steel with a rust preventative coating
• Backboxes are constructed of 22 gauge cold rolled steel,
undercoated to prevent mechanical and acoustical
resonance and finished in a rust preventative coating
• Backboxes meet most local fire codes for use in air
plenum return ceilings
• Backboxes provide acoustic enclosure behind the
speaker for improved sound quality
• Rails are used with both the mounting rings and the
backboxes and are finished in a galvanized coating
Mounting Procedure
• Determine desired speaker location. The speaker should
be located in the center of the ceiling tile
• Use the mounting ring or backbox as a template, cut a
hole in the tile -
- 6 1/2" diameter hole for the 4" speaker
- 10" diameter hole for the 8" speaker
• If the backbox is to be used, run the cable through one of
the four knockouts on the
to the speaker.
• Place the backbox or mounting ring above the ceiling tile.
Place speaker through the tile. Compress springs into
the slots provided in the backbox or mounting rings.
Press speaker to the tile. The torsion springs should pull
the speaker to the tile.

• The backbox rails sit on top of the "T" bar of the ceiling
bridge (see Figure 3). The mounting ring rails lay on the
tile to give it support (see Figure 4). The height of these
bars can be adjusted by loosening the wing nuts. Attach
rails to the backbox by placing rails through the slot
provided on the backbox and securing to the backbox
with a wing nut.
